IMPRovsMl-:Nr IN Looms.Y

.To all trimm it may omwem:

Bc it known that we, OLIVER W. GonnoN and NM'HAN T. FRAME. of Salem,inthecounty of Henry and State rot';lowa, have invented certain new anduseful Improvements in Hand and Power Looms; and we do hereby declarethat the following is a full, clear, and exact description of theconstruction and operation ol' the same, reference heilig had to theaccompanying drawings, made a part of this specitlcation, in which-Figure 1 is an isometrical projection. Fig. 2 is a vertical sectionthrough one of the cases in a plane parallel with the harnessframe onthe line :c .'r, Fig. 3. Fig. 3 is a section through the interior oftheloom, showing au elevation of the inner face of the casing. Fig. 4 is aview ot the end-ot' one of the harness-frames.

The same letters refer to identical parts.

. A is the trame supporting the machinery of the loom. To this frame areatLached the cases B, inclosing thc ends of the harness-frames and thecylinder for actuating thc same. C is the hatten, ot' Ordin-.ryconstruction.

The picker-steil' 'l' is pivotcd' to the middle of the breast-beam, andto this picker-sta` the hook formed drivers l) are attached bym leathernhinge. Below the drivers plays the picker-stati E, around thccylindrical base of which the leathern hinge of the drivers passes. Thishinge is attached in the middle to'the base of the picker-stati'. Thedrivers D nre hooked upon their interior faces, and are held together attheir points by an india-rubber elastic band. The hooks catch upon a pinpassing through a slot in the betten, alternately, as the hatten isthrown back, and by its forward movement they actnatc the picker-statiand communicate motion tov the shuttle. In employing the term forward wemean toindicate motion from the breast-beam toward the loom. 1

To the two ends of the handrnil of the batten are attached, at thejunction with thesword of thc hatten, cords or straps I, passing overulleys in the casing und attached to a lever,

as shown in Fig. 2. This lever moves freely bya collar on thecylinder-gudgeon and carries adog working upon u. ratchet keyed to thecylinder. When this cord I is raised by the motion of thc hatten towardthc breast-bcam it raises the lever, and by the action ofthe dog uponthe ratchet H communicates a. quarterrcvolution to the cylinder. Whenthe hatten returns in the other direction theleveris drawn down hy thcaction of a spring, K, and, moving mi its collar freely. does not movethe cylinder.

F is a cylinder the axis of which is at right angles with the plane ot'the. h.'1rnc'ss-al|at'ts,y

having on its surface eight holcsdrilled in each of four rows, the rowsbeing made atdistances of ninety degrees from one another. These holesare made to receive four pins in each row, to be adjusted according tothe pattern to be worked, and at each revolution these pins give upwardor downward motion to the harnessshafts, as may be desired. The pinsthat give upward motion do not give downward motion, and vice versa. l

L are guides to the harness-shafts, so conningtheshafts thatthe pinswill always strike them as desired.

G are the harnessshafts, the upper and lower longitudinal parts ot'which areframed together by cross-pieces, as shown in Fig. 4. Thesecross-pieces g are made of double the thickness ofthe parts g'g",and theparts g' and g" are halved onto the extremities of the cross-piece g ondifferent sides of the cross-piece, so that the part g'tshall not bedirectly over the part g', but so disposed as that the piu, which iuascending shall strike the part g", shall, indescendiu g, not strike thepart g', and vice versa, the eect ot' which arrangement is tocommunicate a positive motion to the harness-frame both in ascending anddescending. Both ends gI and g" of the horizontal parts oftheharnessshafts project a sncicnt distance beyond the nprigbts g toreceive between them *and be acted'npon by the pins of thepattern-cylinder.

Vie have described the portions peculiar to our loom. The other portionsof the working mechanism are such as are commonly employed for therespective purposes in other looms.

'e do not claim simply raising both ends of the harness-frames bypositive action by means ot' lifting cylinders or cams at both ends ofthe rame,1`or the harness-frames are raised by a positive action in agreat variety of waysV in all looms. Our improvements consist inlowering the harness-frames hy a positive eo tion similar to that bywhich they were raised.

Having now fully explained the construction and operation of ourimprovements in looms,

vhat we claim as onr invention, and seek to secnre by Letters Patent,ic-

1. A device for com mnnicatng motion from the-hatten C to thepicker-atan' E, withont the nseofanxilinrypnlleys. by meansof thedrivers D and exible' hinge, snhstantiallyas set fort-h. 2. Constructingthe harness-shafts G with their uprights g and projecting ends g g", nsand for the purposes set forth.

3. Raising and lowering both ends of the harness-shafts simultaneouslyby n positive action, substantially ns and l'or the purpose oet forth.

y The cylinders F, so arranged as that their axes shall be ni:v rightangles with the planes of the harness-allaite, and by means of pinsthereon giving a positive motion, both ascending and descending, to theharness-shafts.

5. The combination ot' the hatten C, the cord I, lever, and ratchet Hwith the cylinder F, substantially as and for the purposes set forth.

6. The removable guides L, in combination with the harness-shafts G.having eyes, or'tbeir equivalents, for such guides, construct andarranged substantially as and for the purpose set forth.

7. The arrangement ot' the cases B, and the pawl and lever X, andratchet H,cylinder and ha mess-shafts, constructed and combinedsubstantinllr, as set forth. In testimony whereof We have signed ournames lo thisI :specification in the presence of two subscribingwitnesses.
